What I claim is:

1. In a screw-vise consisting of a lower slide with a stationary jaw anda threaded spindle and of a slidable jaw with upper guiding portion, thestationary jaw integral with the lower slide formed of a set of adjacentthin metal-sections connected together by rivet-bolts, said sectionshaving a mutually coincident longitudinal prole of the whole piece,guiding and fastening endplates having shoes and lugs serving at thesame time for clamping the sections together Y by aid of conirnonrivet-bolts.

2. In a screw-vise consisting of a lower slide with a stationary jaw andaj threaded spindle and of aslidablejaw` with upper guiding portion,`the stationary jaw integral with the lowerslide formed of a setro adjacent thin metal-sectionsY connected together by rivet-bo1ts,saidsectionshaving a mutually coincident longitudinal proile of the wholepiece, guiding and Jfastening end-plates having shoes and lugs servingat the saine time for clamping Ythe Sections together by aid of commonrivet-bolts, a guiding sleeve ix'ed within the stationary jawv toprotect the screw-vise spindle from being injured, said spindle beingguided'by a threaded bore provided in the upper slide of the slidablejaw.

In testimony whereof I have signed'my name to this specification. i HUGOVOGL.
